The same happens when a tuple of only two values <i><span data-if="hdevelop" style="display:inline">'sigma_min'</span><span data-if="c" style="display:none">"sigma_min"</span><span data-if="cpp" style="display:none">"sigma_min"</span><span data-if="com" style="display:none">"sigma_min"</span><span data-if="dotnet" style="display:none">"sigma_min"</span><span data-if="python" style="display:none">"sigma_min"</span></i> and

However, in this case a fixed step width of
<i>0.05</i> is used.
</p>
<p>Then, the extracted connecting lines are split at the grid
points and those line segments are selected that start as well as end at a
grid point. Note that edge detectors typically don't work very accurately
in the proximity of edge junctions, and thus in general the connecting lines
will not hit the grid points. Therefore, actually those connecting lines are
split and selected that start at, end at, or pass a grid point at a maximum
distance of <a href="#MaxDist"><i><code><span data-if="hdevelop" style="display:inline">MaxDist</span><span data-if="c" style="display:none">MaxDist</span><span data-if="cpp" style="display:none">MaxDist</span><span data-if="com" style="display:none">MaxDist</span><span data-if="dotnet" style="display:none">maxDist</span><span data-if="python" style="display:none">max_dist</span></code></i></a>. The connecting lines are modified in order to
start and end exactly in the corresponding grid points, and
are returned in <a href="#ConnectingLines"><i><code><span data-if="hdevelop" style="display:inline">ConnectingLines</span><span data-if="c" style="display:none">ConnectingLines</span><span data-if="cpp" style="display:none">ConnectingLines</span><span data-if="com" style="display:none">ConnectingLines</span><span data-if="dotnet" style="display:none">connectingLines</span><span data-if="python" style="display:none">connecting_lines</span></code></i></a> as XLD contours.
</p>
<p>Additionally, <code><span data-if="hdevelop" style="display:inline">connect_grid_points</span><span data-if="c" style="display:none">connect_grid_points</span><span data-if="cpp" style="display:none">ConnectGridPoints</span><span data-if="com" style="display:none">ConnectGridPoints</span><span data-if="dotnet" style="display:none">ConnectGridPoints</span><span data-if="python" style="display:none">connect_grid_points</span></code> calculates for each output XLD
contour its type of transition and stores it in its global attribute
<i><span data-if="hdevelop" style="display:inline">'bright_dark'</span><span data-if="c" style="display:none">"bright_dark"</span><span data-if="cpp" style="display:none">"bright_dark"</span><span data-if="com" style="display:none">"bright_dark"</span><span data-if="dotnet" style="display:none">"bright_dark"</span><span data-if="python" style="display:none">"bright_dark"</span></i>. The attribute is set to <i>1.0</i>, if the
connecting line forms a bright-dark transition (left to right, viewed from
start point to end point), otherwise it is set to <i>0.0</i>. For further
information about global contour attributes see
<a href="get_contour_global_attrib_xld.html"><code><span data-if="hdevelop" style="display:inline">get_contour_global_attrib_xld</span><span data-if="c" style="display:none">get_contour_global_attrib_xld</span><span data-if="cpp" style="display:none">GetContourGlobalAttribXld</span><span data-if="com" style="display:none">GetContourGlobalAttribXld</span><span data-if="dotnet" style="display:none">GetContourGlobalAttribXld</span><span data-if="python" style="display:none">get_contour_global_attrib_xld</span></code></a>.
</p>
<h2 id="sec_attention">注意</h2>
<p>For a reliable determination of the type of bright-dark transition as well
as for the following rectification, it is necessary that each connecting
line has at least three contour points. Therefore, connecting lines with
only two contour points are not returned. Note, that the parameter
<a href="#MaxDist"><i><code><span data-if="hdevelop" style="display:inline">MaxDist</span><span data-if="c" style="display:none">MaxDist</span><span data-if="cpp" style="display:none">MaxDist</span><span data-if="com" style="display:none">MaxDist</span><span data-if="dotnet" style="display:none">maxDist</span><span data-if="python" style="display:none">max_dist</span></code></i></a> has a substantial influence on the length of the returned
connecting lines, because all contour points of a possible connecting
line that are closer than <a href="#MaxDist"><i><code><span data-if="hdevelop" style="display:inline">MaxDist</span><span data-if="c" style="display:none">MaxDist</span><span data-if="cpp" style="display:none">MaxDist</span><span data-if="com" style="display:none">MaxDist</span><span data-if="dotnet" style="display:none">maxDist</span><span data-if="python" style="display:none">max_dist</span></code></i></a> to a grid point are replaced by
one single contour point. If <a href="#MaxDist"><i><code><span data-if="hdevelop" style="display:inline">MaxDist</span><span data-if="c" style="display:none">MaxDist</span><span data-if="cpp" style="display:none">MaxDist</span><span data-if="com" style="display:none">MaxDist</span><span data-if="dotnet" style="display:none">maxDist</span><span data-if="python" style="display:none">max_dist</span></code></i></a> is too big, some of the
connecting lines might get lost.</p>
